Our prescription of Minkowskian holography draws heavily on the evolution of AdS/CFT from the seminal work of Brown and Henneaux, who famously computed the asymptotic symmetries of AdS\(_3\)  to obtain two copies of the Virasoro algebra that have since been understood as the global symmetries of the dual 2d field theory. Following this lead, it has been proposed [1]}, [2]} that the dual of 3d Minkowski spacetimes is a 2d field theory living on \({I}^\pm \)  which has BMS\(_3\)  as its underlying symmetry. We shall call these field theories BMS field theories or BMSFTs in short.
